SAFETY
Thank you for selecting the Martin MAC 250 or the MAC 250+. Both the MAC 250 and the MAC 250+ are yokemounted profile spotlights that are designed around a 250 watt discharge lamp. They provide:
•
•
•
•
•
•
•
12 saturated dichroic colors
8 replaceable rotating gobos
3-facet rotating prism
variable focus
strobe effects
0 to 100% dimming
accurate 16-bit movement.
In addition, the standard MAC 250 provides 4 user-configurable beam angles from 12.1° to 23.3°. The MAC 250+ provides gobo indexing, interchangeable color filters, and an 18.3° achromatic lens system. High-performance optics,
attractive design, modular construction and numerous user-friendly features make these Martin fixtures well suited for
any effect lighting application calling for a compact, hard-focusing 250 watt fixture.
Safety precautions
The MAC 250 and MAC 250+ are for professional use only. They are not for household use. They present risks of
injury due to electric shock, heat and ultraviolet radiation burns, lamp explosion, falls, high-intensity light, and fire.
Read this manual before powering or installing the fixture, follow the safety precautions listed below and observe
all warnings in this manual and printed on the fixture. If you have questions about how to operate the fixture safely,
please contact your Martin dealer or call the Martin 24-hour service hotline for assistance.
•
ALWAYS disconnect the fixture from AC power before removing or installing the lamp, fuses, or any part; and when
not in use.
•
Allow the fixture to cool for at least 5 minutes before replacing the lamp.
•
Keep all combustible materials (for example fabric, wood, paper) at least 0.3 meters (12 inches) away from the fixture.
Keep flammable materials well away from the fixture.
•
For protection against dangerous electric shock, always ground (earth) the fixture electrically. Use only a source of AC
power that complies with local building and electrical codes. Do not expose the fixture to rain or moisture.
•
Ensure that the air flow through fans and vents is free and unobstructed.
•
When suspending the fixture above ground level, verify that the structure can hold at least 10 times the weight of all
installed devices and secure the fixture with an approved safety cable. Block access below the work area whenever
installing or removing the fixture.
•
Refer any service operation not described in this manual to a qualified technician.
•
Do not illuminate surfaces within 0.3 meters (12 inches) of the fixture.
•
Never place filters or other materials over the lens.
•
Do not operate the fixture if the ambient temperature (Ta) exceeds 40° C (104° F).
•
Replace the lamp as soon as it becomes defective or worn out, or before usage exceeds the maximum service life.
•
Do not stare directly into the light.
•
Never operate the fixture without all lenses and covers installed: an unshielded lamp can explode without warning and
emits dangerous UV radiation that can cause burns and eye damage.
•
Do not modify the fixture or install other than genuine Martin accessories and upgrade kits.

To i n s t a l l a l a m p
1. Remove the 2 Phillips screws from the lamp socket assembly. Pull the lamp and socket out of the head.
2. Remove the old lamp, if any, from the socket.
3. Holding the new lamp by its ceramic base (do not touch the glass), align the small pin with the
small hole and insert the lamp squarely into the socket. Make sure that the 4 small projections on the
base contact the face of the socket.
4. Clean the glass bulb with the cloth supplied with the lamp, particularly if your fingers touched the
glass. A clean, lint-free cloth wetted with alcohol may also be used.
5. Gently insert the assembly, making sure the lamp fits through the opening in the reflector. Replace
the 2 screws.
6. The reflector is pre-adjusted at the factory; however, precise alignment to compensate for variations
between lamps may improve performance. See “Optimizing reflector alignment” on page 15.
Pow e r i n g
WA R N I N G !
For protection from dangerous electric shock, the fixture must be grounded
(earthed). The AC mains supply shall be fitted with a fuse or circuit breaker and
ground-fault protection.
1. Verify that the voltage and frequency settings match the local AC supply. The factory settings are printed on
a label under the base. Check Table 7 on page 20 to verify that these settings are correct for your local AC
voltage. Operating at the incorrect power setting can result in poor light output, greatly reduced lamp life,
overheating and damage to the fixture. Refer to “Changing voltage and frequency settings” on page 20 if the
settings need to be adjusted.
2. Install a grounding-type cord cap that fits your supply on the power cable. Following the manufacturer’s instructions, connect the yellow/green wire to the ground (earth) pin, the blue wire to the neutral pin, and the brown wire to the live pin. The table shows some possible pin identification schemes;
if the pins are not clearly identified, or if you have any doubts about proper installation, consult a
qualified electrician.

3. Verify that the supply cable is undamaged and rated for the current requirements of all connected
devices.
4. Plug the prepared power cable into the 3-prong IEC inlet and a grounded AC power supply. Do not
connect the fixture to a dimmer system.

Rigging
The MAC 250 and MAC 250+ include a clamp mounting bracket to which 1 or 2 rigging clamps (not included) can be
bolted. The clamp mounting bracket fastens to the base as shown with 1/4-turn fasteners.
Figure 2: Clamp mounting bracket
WA R N I N G !
Always use an approved safety cable.
The 1/4-turn fasteners are locked only when turned fully clockwise.
1. Verify that the clamps are in good condition and can bear at least 10 times the weight of the fixture. Bolt
clamps to the bracket with a grade 8.8 (minimum) M12 bolt and lock nut, or as recommended by the clamp
manufacturer, through the 13 mm holes in the clamp mounting bracket.
2. Align the clamp mounting bracket with any 2 key slots on the base. Insert both locking pins into the
slots and turn both levers a full 1/4 turn clockwise to lock.
3. Verify that the structure can bear at least 10 times the weight of all installed fixtures, clamps, cables,
auxiliary equipment, etc.
4. Working from a stable platform, clamp the fixture to the structure.
5. Install a safety cable that can bear at least 10 times the weight of the fixture securely to the structure
and anchor the cable to the dedicated attachment point on the base. The attachment point is
designed to fit a carabiner clamp.
Connecting the serial data link
The MAC 250 and MAC 250+ have locking 3-pin data input and output sockets that are wired for use with DMX
devices, that is, pin 1 to shield, pin 2 to cold (-) and pin 3 to hot (+). As some devices have 5-pin connectors, or 3-pin
connectors with reversed polarity on pins 2 and 3, the following adaptor cables may be required.

1. Connect the controller’s output to the fixture’s data input. For a DMX controller with 5-pin output, use a
cable with a 5-pin male and a 3-pin female connector, such as P/N 11820005. For a DMX controller with 3pin output, use a 3-pin cable such as the one included. For a Martin RS-485 protocol controller, use a
phase reversing cable or reconfigure the pin-out as described on page 19.
2. Connect the output of the fixture closest to the controller to the input of the next fixture. When connecting a fixture with pin 3 hot to a fixture with pin 3 cold, use a phase-reversing adaptor.
3. To terminate the link, insert a male 120 Ω XLR termination plug in the output of the last fixture.

MAC 250 and MAC 250+
Tips for building a serial link
•
Use shielded twisted-pair cable designed for RS-485 devices: standard microphone cable cannot transmit DMX data
reliably over long runs. For links up to 300 meters (1000 ft.) long, you can use 24 AWG, low capacitance, 85-150 ohm
characteristic impedance, shielded cable with 1 or more twisted pairs. For runs up to 500 meters (1640 ft.) use 22 AWG
cable. Use an amplifier if the serial link exceeds 500 meters.
•
Never use a “Y” connector to split the link. To split the serial link into branches use a splitter such as the Martin 4Channel Opto-Isolated RS-485 Splitter/Amplifier.
•
Do not overload the link. Up to 32 devices may be connected on a serial link.
•
Terminate the link by installing a termination plug in the output socket of the last fixture on the link. The termination
plug, which is simply a male XLR connector with a 120 ohm, 0.25 watt resistor soldered between pins 2 and 3, “soaks
up” the control signal so it does not reflect back down the link and cause interference. If a splitter is used, terminate
each branch of the link.

Table 3: Control modes
The fixture address and operating mode must be selected before the MAC 250 or MAC 250+ will respond to the controller. DMX mode 4 provides full control and is recommended unless channels are limited. See “DMX-512 control”
on page 12 for factors to consider when selecting other DMX modes.
The address, also known as the start channel, is the first channel used to receive instructions from the controller. For
independent control, each fixture must be assigned its own address and non-overlapping control channels. Two fixtures
may share the same address only if they are to respond identically: they will receive the same instructions and individual control will not be possible.
If automatic protocol detection (AUTO ) is O N , the fixture automatically switches to DMX or Martin mode after
interpreting the control signal. This allows you to set the fixture up for both DMX and Martin controllers. If it is O FF,
the default, the operating mode must match the controller. Note: automatic protocol detection does not detect the DMX
mode (1, 2, 3, or 4) setup on the controller.
1. Apply power to the MAC 250 or MAC 250+. Press [MENU] on the control panel to enter the main menu.
2. Select A ddR using the arrow keys. Press [ENTER].

section 4
OPERATION
This section describes the effects and how personality settings affect their behavior. Selecting personalities from the
control panel is described in the previous section.
DMX-512 control
The MAC 250 and MAC 250+ can be operated with DMX-512 controllers in 4 modes that combine vector and/or tracking control with 8-bit or 16-bit pan/tilt resolution.
Tr a c k i n g c o n t r o l
With tracking control, the speed at which effects move is set by programming a cross-fade time on the controller. The
controller divides the move into steps and updates the fixture with small changes at the rate required to achieve the
fade. The fixture tracks the changes and averages them with a digital filter algorithm to provide smooth movement at
all speeds.
This algorithm is adjustable to compensate for controllers that calculate position changes unevenly. In most cases the
default settings work well. If movement is not satisfactory there are 2 parameters that can be adjusted. The first is the
calculation method used and is selected under PE RS/ TRA C/M OdE . MOd 1 , the default, calculates speed based
on the absolute value of the change in DMX; it is the best choice with controllers that calculate intermediate positions
that are close to the line of travel. MOd 2 uses the real value of the DMX delta to calculate speed and is better if the
intermediate positions stray significantly from the line of travel.
The second parameter is the number of position updates used to calculate speed. The level is adjustable between 1 and
10 under PE RS/ TRAC /CA L . Increasing the number of samples increases the distance over which speed is calculated, making movement smoother but less responsive to sudden changes.
The ideal settings for both parameters will vary from controller to controller: experiment for best results.
Ve c t o r c o n t r o l
With vector control, you set the speed on a speed channel. This provides a way to control speed on controllers without
cross-faders. Vector control also provides smoother movement, particularly at slow speeds, with controllers that send
slow or irregular tracking updates, plus a “blackout speed” and overrides of the shortcut and pan/tilt speed personality
settings. When using vector speed, the cross-fade time must be 0.
Tracking control can be enabled in vector mode by setting one or both of the speed channels to “tracking speed.”
8-bit versus 16-bit pan/tilt resolution
With 8-bit pan/tilt resolution, pan and tilt are divided into 256 equal increments. Finer position control and smoother
movement are provided in 16-bit mode, which divides pan into 40,192 positions and tilt into 43,008 positions.
Mar tin RS-485 con trol
The MAC 250 is fully supported by the Martin 3032 controller with version 2.05 or higher software. The MAC 250+
may be set up on the 3032 as a MAC 250: gobo indexing, however, is not supported. To respond to the 3032, Martin
mode must be selected or automatic protocol detection must be enabled as described on page 10.
Controllable effects
All mechanical effects are reset to a home position when the fixture is powered up. They can also be reset via DMX.
Accidental resets can be prevented by turning DMX Reset (PERS /dR ES ) off.
An on-the-fly position correction system automatically corrects the position of the color and gobo wheels; this feature
can be disabled by turning Effects Feedback (PE RS/ EFFb ) off.
General operation may be optimized for speed or quietness with the Studio Mode setting (PER S/S TUd ).
Lamp
With the default setting, the lamp remains off until a “lamp on” command is sent from the controller. Note: A peak of
electric current that can be many times the operating current is drawn for an instant when striking a discharge lamp.
Striking many lamps at once may cause a voltage drop large enough to prevent lamps from striking or draw enough
12
MAC 250 and MAC 250+
current to trip circuit breakers. If sending “lamp on” commands to multiple fixtures, program a sequence that strikes
lamps one at a time at 5 second intervals.
The fixture automatically strikes the lamp within 90 seconds of being powered on if the Automatic Lamp On setting
(PER S/AL ON ) is turned on. A delay determined by the fixture address staggers lamp strikes to prevent excessive
voltage drop and current draw.
The lamp can be turned off from the controller. Note: the lamp cannot be restruck for 8 minutes after being turned off.
Accidental “lamp off” commands can be prevented by turning the DMX Lamp Off setting (PER S/d LOF ) off.

Table 4: Color positions
The MAC 250 and MAC 250+color wheel provides a 5500 to 2900K color temperature correction (CTC) filter and 11
dichroic color filters. The wheel can be scrolled continuously - allowing for split color effects - or in steps, and rotated
randomly or continuously in both directions at different speeds.
The Shortcuts setting (PE RS/S CUT ) determines whether or not the wheel takes the shortest path to the next position; this setting may be overridden on the speed channel in vector mode. Setting the effects speed to “blackout” causes
the shutter to black out the light while the wheel is moving.
The color filters on the MAC 250+ are interchangeable. See page 16.

Table 5: Gobo positions
The MAC 250 and MAC 250+ has 8 rotating gobo positions plus an open position. Each gobo rotates and/or “shakes” at
varying speeds. Gobos and shake are selected on channel 4; rotation is set on channel 5. The gobo wheel also rotates
continuously in both directions at variable speed.
Operation
13
The MAC 250+ provides gobo indexing as well. Select the gobo on channel 4, between the DMX values of 5 and 44,
and set the position on channel 5. The gobo type setting (P ERS /GTY P ) automatically defaults to IN dX in the
MAC 250+ to enable this feature. It defaults to S Td in the MAC 250.
The Shortcuts setting (PE RS/S CUT ) determines whether or not the wheel takes the shortest path to the next position; this setting may be overridden on the effects speed channel. Setting the speed to “blackout” causes the shutter to
black out the light while the wheel turns.
To change the gobos, see “Rotating gobos” on page 15.
Dimmer / shutter
The mechanical dimmer/shutter system provides full, high-resolution dimming, “instant” open and blackout, random
and variable strobe effects, and random and variable pulses in which the dimmer snaps open and slowly dims or snaps
closed and slowly opens. Pulse and random strobe effects can be disabled by switching DMX Macros (PER S/
dMA C ) off.
The Dimmer Mode (PER S / dMO d ) setting allows you to select between linear or simulated tungsten fade curves.
The fade time must be 0 to simulate tungsten dimming.
Focus
The beam may be focused from approximately 2 meters (6.5 feet) to infinity. The MAC 250’s default beam angle is
17.5°; see page 17 for additional options. The MAC 250+ has a different optical system that uses achromatic lenses. It
provides a beam angle of 18.3°.
Rotating prism
The 3-facet prism rotates in both directions at varying speeds. There are 8 preprogrammed macros that combine prism
and gobos. These can be disabled by switching DMX Macros (PE RS/d MAC ) off. Setting the speed to “blackout”
causes the shutter to black out the light while the prism moves in and out.
Pa n a n d til t
The yoke pans 540° and the head tilts 289°. Movement may be optimized for speed by setting the pan/tilt speed setting
(PER S / PTSP ) to FAS T, or for smoothness by setting it to SLOW . This setting may be overridden on the speed
channel in vector mode. Setting the speed to “blackout” causes the shutter to black out the light while the head is moving. The pan and tilt channels can be inverted and/or swapped using the pan/tilt menu (PE RS / PAT I ).

BASIC SERVICE
The MAC 250 and MAC 250+ operate under challenging conditions presented by heat, humidity, dust, and touring.
Excessive dust, grease, and smoke fluid buildup degrades performance and causes overheating and damage that is not
covered by the warranty. The MAC 250 and MAC 250+ require regular maintenance to keep performing at their peak.
The schedule will depend on the application and should be discussed with your Martin distributor. Refer any service
that you are not qualified to perform to a professional technician.
WARNING!
Removing covers exposes dangerous live electrical circuits, hot surfaces, and a
lamp under high pressure. Procedures requiring the removal of any cover shall
be performed by professional users or technicians only. Disconnect the fixture
from AC power and allow it to cool before removing any cover.
Replacing the lamp
If the lamp becomes difficult to strike, it probably needs to be replaced. To reduce the
risk of lamp explosion, which may damage the fixture, do not exceed the lamp’s rated
life (2000 hours) by more than 25 percent.
Refer to page 5 for the lamp replacement procedure. After installing the lamp, reset the
lamp usage counters as described on page 10.
Optimizing reflector alignment
The reflector is aligned at the factory. Due to differences between lamps, however, fine
adjustment may improve performance.
1. Strike the lamp and focus the light on a flat surface.
2. See Figure 1 on page 4. Center the hot-spot (the brightest part of the
beam) by turning the 3 adjustment screws one at a time with a 3 mm Allen
wrench. If there is no hot-spot, adjust the reflector until the light is even.
3. To reduce a hot-spot, “push” the reflector out by turning all 3 screws counterclockwise 1/4-turn at a time until the light is evenly distributed.
4. If the light is brighter around the edge than it is in the center, or if light output is low, the lamp is too far back in the reflector. “Pull” the reflector in by
turning the screws clockwise 1/4-turn at a time until the light is bright and
evenly distributed.
Figure 5
Rotating gobos
Custom glass gobos for the MAC 250 and MAC 250+ should be made with any
non-reversible graphics true on the coated side. Complete gobo specifications are
listed on page 27. Do not use chrome-coated glass gobos: they absorb more heat
than enhanced aluminum gobos and are likely to break or oxidize.
Changing gobos
1. Disconnect the fixture from AC power and allow it to cool. Remove the top
head shell as shown in Figure 5.
2. Turn the gobo wheel until the gobo lines up with the access hole.
Squeeze the ends of the retention spring together and remove. Push
the gobo out from the back.
3. Insert the new gobo. See Figure 7 for proper orientation.

Beam angle options
The standard MAC 250 lens system can be configured for 4 beam angles ranging from 12.1° to 23.3°. The beam angle
in the default 4-lens configuration is 17.5°. Other beam angles are achieved by removing lenses and positioning the
dimmer module as shown below. Note: dimming will be somewhat less even in the 12.1° configuration.
To calculate the projected size of an image, divide the gobo’s image diameter by the focal length and then multiply by
the distance in meters.

Cleaning
Optical components
Use care when cleaning optical components. The surface on dichroic filters is achieved by means of special multi-layer
coatings and even small scratches may be visible. Residues from cleaning fluids can bake onto components and ruin
them.
1. Allow the components to cool completely.
2. Wash dirty lenses and filters with isopropyl alcohol. A generous amount of regular glass cleaner may
also be used, but no residues may remain.
3. Rinse with distilled water. Mixing the water with a small amount of wetting agent such as Kodak
Photoflo will help prevent streaking and spotting.
4. Dry with a clean, soft and lint-free cloth or blow dry with compressed air.
Fans
To maintain adequate cooling it is important that the fans be cleaned of dust and dirt periodically. Use a soft brush, vacuum, or compressed air.
Lubrication
Use silicone lubricant, Martin P/N 37302003 (500 ml) or P/N 37302004 (200 ml, in applicator bottle). No other lubricant is approved for use. When applying lubricant, always remove excess and do not get oil on other parts.
Check the focus mechanism when the head is open and apply a drop of lubricant to the 3 metal slides if movement is
rough.
Lubricate the rotating-gobo bearings if movement is rough on slow rotation or if they become noisy. Apply a few drops
of oil to each bearing from the lamp side of the wheel.

Replacing fuses
Po w e r s u p p ly f u s e s
The fuses for each of the 3 low-voltage power supplies are located on the printed circuit board. If one of the circuit
board LEDs does not light, one of these fuses may be blown.
1. Disconnect the fixture from AC power. Remove the 2 Philips screws from the plastic cover on the arm opposite the side with the visible motor and pull off the cover.
2. Locate and replace the defective fuse with one of the same rating. The fuses are shown on the PCB
layout diagram; their values are listed on page 27.
3. Replace the cover before applying power.
Main fuse
The main fuse holder is built in to the mains input socket. Never replace the fuse with one of a different rating!
1. Unplug the mains cable from the input socket.
2. Pry open the fuse holder and remove the fuse.
3. Replace the fuse with one of the same type and rating. The fuse rating is listed on serial number
label.
4. Close the fuse holder and replace the mains cable.
Changing the XLR pin-out
The signal polarity of pins 2 and 3 on the XLR connectors
can be reversed, allowing the fixture to be connected
directly to Martin devices wired with pin 3 cold (-).
Optionally, a phase-reversing cable may be used.
1. Disconnect the fixture from AC power. Remove the 2
Philips screws from the plastic cover on the arm
opposite the side with the visible motor and pull off

Updating software
The MAC 250 and MAC 250+ operate with the same software. Updates are available from your Martin dealer and the
Martin Professional web site. Please read the update notes included with the software. Note: the software automatically defaults to the correct gobo type setting (P ERS /GT YP ) in unmodified fixtures.
Normal upload
Update software is uploaded to the MAC 250 and MAC 250+ using a Martin uploader such as the MPBB1. The
uploader is connected to the fixture just like a controller. Under normal conditions, software can be installed from a
remote location - there is no need to set the MAC 250 and MAC 250+ to boot mode. Please refer to the uploader manual
for further instructions.
Boot mode upload
If the data is corrupted during transmission, a check-sum error (CS ER ) occurs and after 15 seconds the fixture
switches to boot mode (U PLd ) and is ready for a boot mode upload as described in the uploader manual.
If a software upload is interrupted, the fixture must be turned off for at least 10 seconds before a new upload can be
attempted. When powered on, a check-sum error occurs and the fixture goes into boot mode, ready for a second upload
attempt. Select boot mode upload on the uploader.
If there is no functional software in memory, the fixture must be set to boot mode manually. If the control panel works,
select UP Ld from the U TIL menu and confirm when S URE is displayed by pressing [ENTER].

What to do
AUTO (Automatic protocol detection error)
Automatic protocol detection is enabled
and there is no control input.
LERR (Lamp error)
... the lamp doesn’t ignite within 10 min- • Check the lamp
utes of receiving the ‘Lamp ON’ com• Check voltage and frequency settings
mand.
MERR (Memory error)
...the EEPROM memory cannot be
read.
• Contact service technician.
CSER (Check-sum error)
...a software upload is unsuccessful.
• Reload software, see page 20.
****
... there is no communication between
the control panel and motherboard.
This appears briefly when switching on
the fixture.
• Check fuses.
• Check cable between control panel
and motherboard.
• Reinstall software.
• Contact service technician.
ShER (Short error)
... the fixture detects the lamp is ON but
no ‘Lamp ON’ command has been
received. This can occur if the lamp
relay is stuck.
• The fixture may be operated but
remote lamp on/off may be effected.
• Contact service technician.
Hot (Hot lamp)
... you attempt to strike the lamp within
8 minutes after having switched it off.
The fixture will store the ‘Lamp ON’
instruction and strike the lamp once the
8 minutes period has elapsed.
• Wait until the lamp strikes.
FbEP (Feedback error pan)
FbET (Feedback error tilt)
FbER (Feedback error pan/tilt)
...pan (FbEp), tilt (FbET) or both (FbER)
feedback circuits are malfunctioning.
• The fixture will still operate, though
with reduced maximum speed to prevent the fixture from losing track of its

Tr o u b l e s h o o t i n g
Problem
One or more of the fixtures
is completely dead.
Fixtures reset correctly but
all respond erratically or not
at all to the controller.
Fixtures reset correctly but
some respond erratically or
not at all to the controller.
Magnetically indexed effect
resets correctly but wanders after fixture reaches
operating temperature.
No light and “LERR” error
message displayed.
Lamp cuts out intermittently.
25
Probable cause(s)
Remedy
No power to fixture.
Check that power is switched on and cables are
plugged in.
Primary fuse blown.
Replace fuse.
Secondary fuse(s) blown (located on
PCB inside base).
Check fuses on PCB and replace.
The controller is not connected.
Connect controller.
XLR pin-out of the controller does not
match pin-out of the first fixture on the
link (i.e. signal is reversed).
Install a phase-reversing cable between the
controller and the first fixture on the link.
Bad data link connection
Inspect connections and cables. Correct poor
connections. Repair or replace damaged
cables.
Data link not terminated with 120Ω termination plug.
Insert termination plug in output jack of the last
fixture on the link.
Incorrect addressing of the fixtures.
Check address and protocol settings.
One of the fixtures is defective and disturbs data transmission on the link.
Bypass one fixture at a time until normal operation is regained: unplug both connectors and
connect them directly together. Have the defective fixture serviced by a qualified technician.
XLR pin-out on fixtures does not match
(pins 2 and 3 reversed).
Install a phase-reversing cable between the fixtures or swap pins 2 and 3 in the fixture that
behaves erratically.
Effect wheel or magnetic sensor
requires mechanical adjustment.
Disable effects feedback. Contact Martin technician for service.
The ballast and transformer settings do
not match local AC voltage and frequency.
Disconnect fixture. Check ballast and transformer settings and correct if necessary.
Lamp missing or blown
Disconnect fixture and replace lamp.
Fixture is too hot.
Allow fixture to cool.
Reduce ambient room temperature.
Recalibrate temperature sensors.
The ballast and transformer settings do
not match local AC voltage and frequency.
Check ballast and transformer settings and correct if necessary.
